airbrushing

does anyone know how to airbrush?...if so how hard is it for someone who is artistic or can at least draw well?  im interested in learning...but dont know a whole lot about the process....please help!

its harder to brush than u think, yes the whole "im a well talented artist with a pencil" comes into play, but u need a dual action brush just to be anywhere close to capable, (dual action controls paint and air flow) u can a little apint and a lot of air or a little air and a lot of paint,but the hardest thing about brushing if ur a good artist already is working the dual action part
